java - 象鸟mvn包报错

Question

我已经在我的系统中安装了 hadoop 2.2。我想使用 Elephant-Bird jar 。运行“mvn package”时出现以下错误。

错误:

---

我在 pom.xml 中添加了以下代码，但仍然存在错误。

<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-lang3</artifactId>
    <version>3.1</version>
</dependency>

我该如何解决这个错误？

系统配置

Thrift version 0.9.1

Apache Maven 3.0.5 (r01de14724cdef164cd33c7c8c2fe155faf9602da; 2013-02-19 19:21:28+0530)
Maven home: /usr/lib/mvn/apache-maven-3.0.5
Java version: 1.7.0_25, vendor: Oracle Corporation
Java home: /usr/lib/jvm/java-7-openjdk-amd64/jre
Default locale: en_IN, platform encoding: UTF-8
OS name: "linux", version: "3.5.0-43-generic", arch: "amd64", family: "unix"

Hadoop 2.2.0.2.0.6.0-76

Answer 1

通过从 http://archive.apache.org/dist/thrift/0.7.0/thrift-0.7.0.tar.gz 下载将 Thrift 从 0.9.1 更改为 0.7.0 .提取并进入提取的文件夹。然后输入以下命令:

• chmod +x ./configure
• ./配置
• 制作
• sudo 进行安装

通过键入 thrift -version 检查 thrift 版本。这应该返回 "Thrift version 0.7.0"

然后转到 elephant-bird 文件夹并输入“mvn -Dmaven.test.skip=true package”

注意:跳过测试用于某些测试失败。跳过测试选项解决了这个问题。

编辑:Pig 在为 JsonLoader 编译加载语句时抛出错误，因为未找到 json-simple-1.1.1.jar。谷歌 jar ，你可以很容易地找到它。 (由于信誉低于 10，无法发布链接)

并且在启动有关 hadoop-compat 的 pig 作业时抛出错误。下载 http://repo1.maven.org/maven2/com/twitter/elephantbird/elephant-bird-hadoop-compat/4.4/elephant-bird-hadoop-compat-4.4.jar(也可以在 /hadoop-compat/target/elephant-bird-hadoop-compat-4.4-SNAPSHOT.jar 中找到

)

注册 4 个 Jars 以在 Pig 中使用 Elephant-Bird 插件。
